Scope before conclusions

This page covers the exact database record “Contour5 Mattress · Firm · 12.5".” A documented option within this mattress model. Other heights or comfort choices remain on the same page unless the brand markets them under a different mattress name. Family-level evidence is used only where the public sources describe a shared construction; exact-configuration evidence is labeled separately. Nappedia has not slept on, opened, or laboratory-tested this mattress.

Editorial synthesis

Evidence behind the conclusion

Analysis

Firm 12.5 inches Saatva Contour5; other feels and heights may perform differently.

Contour5 Mattress · Firm · 12.5" is documented as memory-foam mattress with a firm feel and 12.5 inches profile. The page uses the current or historical documents listed below. Independent findings appear only when the tested version is identified; missing results are marked as unknown.

Who the cited evidence may support

These are research signals, not a comfort guarantee.

People seeking slower, deeper memory-foam contouring with a selectable medium or firm feel.
Shoppers who value published densities for the two primary memory-foam layers.

What to check before choosing

These limitations may change whether the mattress fits.

The model is distinct from the still-active Loom & Leaf family.
Cooling language is manufacturer positioning unless tied to an independent test.
Support-foam density and a full adhesive/material inventory are not published.
Verify the exact Firm / 12.5 inches configuration before relying on family-level findings.

Confidence statement

High confidence in the configuration identity and current public dimensions; medium confidence in the published construction; performance confidence depends on whether a source tested this exact configuration.

Independent or cross-source context

Saatva publishes Medium at 5-7/10 and Firm at 8/10. Sleep Foundation separately evaluated both test samples as Medium Firm 6 and Firm 8, but its samples were reported as 12 inches rather than the current official 12.5 inches.

Family-level context; transfer to the exact configuration is limited and labeled.⁶

Method, sample, and source kept attached

Performance evidence matrix

A result describes a particular test method and sample. When reputable reviewers disagree, this file records the disagreement instead of inventing a consensus score.

Forensic Sleep Mechanics • coil deflection

Body Mass Load:

Shoulder: 28mm / Lumbar: 18mm

Zoned Biomechanics (Hooke's Law): Differential wire gauges isolate body mass zones. While plush 16.0 AWG coils allow deep shoulder contouring (28mm), reinforced 14.5 AWG lumbar springs resist pelvic rotation under heavy loads, arresting sag at 30mm to maintain neutral lordotic alignment (Δy ≈ 0).

Simulated Hooke’s law pocket coil deflection across anatomical body load distributions.
